HENRY GUTEI, OF NEW YORK, N. Y.

VENTILATING VA LVE FOR FERM ENTlNG-CASKS.

SPECIFICATION forming part of Letters Patent No. 275,764, dated April 10, 1883,

Application filed February 16, 1882.

To all whom it may concern 4 Be it known that I, HENRY GUTH, a citizen of the United States, and a resident of New York, in the county of New York and State of New York, have invented a new and valuable Improvement inVentilating-Valves for Fer menting-Gasks; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters and figures of reference marked thereon.

Figure 1 of the drawings is a representation of a front view of my improvement in ventilating-valvcs. Fig. 2 is a sectional view of one of the valves.

This invention has relation to ventilatingvalves for fermenting-casks; and it consists in the novel construction and arrangement of parts, as will be hereinafter fully described, and particularly pointed out in the claim.

In the annexed drawings, the letter A designates a stationary stand having a shelf or ledge, B, which is perforated or provided with seats 0 to receive the ventilating-valves D. Each ventilating-valve is provided with a reciprocating inverted valve-cap, and within the same a tube having guides, substantially as described in Letters Patent film-225,368, granted to me on the 9th of March, 1880. The lower end of said tube is made long enough to be inserted through the perforation c of the shelf B, and is usually provided with a thread, 0, at

this point to insure a secure fastening. Below this part 0 the valve is provided with a nipple, g, or other fastening for the attachment of a tube, H, which is usually made of rubber hose, but may consist of block-tin or other metallic piping.

Kindicates a double or other stop-cock, which is inserted into the cask, which may be (No model.)

placed on the beams m of the stand below the ledge or shelf B; or the cask may be located in the neighborhood of the shelf.

The lower end of the tube H is designed to be connected to the stop-cock, which is attached to the cask as indicated in the drawings. The valve D is provided with an exterior bearing, to, for weights 2, which are adjustable thereon, in order to establish the fermentation in the cask under any desired pressure. The valve also efl'ectuall y prevents bursting of the cask. lt also'prevents the beer from turning sour or stale, and obviates the rising of deposits in the cask, which often occurs when there is a quick change of atmospherical conditions. The pressure on the valve must,however, be carefully regulated, and the valve must be free to work in a vertically-reciprocating manner. Therefore the valve is fixed in the stationary shelfor stand, so that its movements will be always steady and correct, the movable cask being connected to it by a tube and stop-cock.

Having described this invention, what I claim, and desire to secure by Letters Patent,

The combination, with a stationary stand provided with a perforation or seat, 0, of a ventilating-valve, D, connected to said seat, and provided with a threaded projecting stem, g, and a tube, H, and a double stop-cock, K, adapted to be inserted in the cask containing the fermenting liquor, whereby each cask in the stand may be provided with a separate ventilating-valve, substantially as specified.

In testimony that I claim the above I have hereuntosubseribed my name in the presence of two witnesses. v
